This pivotal mounting' of Referring to said drawings, 1 represents the the carrier 2 may be secured in many ways;

printing-frame, 2 its carrier, and 3 the supbut l prefer the simple means shown, consistport on which the latter is mounted. The ing of a bolt 16, projecting upward through printing-frame shown consists of a frame 4f, an opening in support 3 and passing through an opening in the base of the carrier 2. the

upper end of said bolt being threaded to re-Y ment referred to of the printing-frame 1, the

latter is horizontally pivoted in vertical standards 18 of its carrier 2, so that the frame may be swung to and from the support 3 into any angular position desired, as shown in Fig's. 1 and 2. This pivotal connection of the printing-frame 1 in the present case is providednot only for the purpose of angularly adjusting the frame and its negative relatively to the light, but also for the purpose of enabling the operator to swing the frame 1 to a substantially horizontal position (seeFig. 2) with its rear side upward, so that he can conveniently and quicklyremove from the frame the sheets of photographicprinting paper as vprinted and keep the frame supplied with sheets to be printed upon. This is a feature of considerable importance, as the printingpaper of the present day is very rapid, and with a frame capable of being swung into the convenient position shown a great saving of time is effected and the product of the printing apparatus may be materially increased.

It is desirable when the frame` 1 is swung to the horizontal position shown that some means be provided for holding' and steadying it in that position. Means for this purpose are shown in the present case, consisting' of a stop 19 on an arm 20, secured to one of the standards 18 of carrier 2 and which engages and arrests the downward movement of the printing-frame when swung to this horizontal position, upward movement of the frame from this position being prevented by a pin 21, which as the frame is swung downwardly presses the arm 2O (which is-of spring metal) to one side and as the frame reaches .horizontal position enters an opening 22 in said arm, as shown in Fig. 2. The frame 1 is released in order to return it to or toward vertical position by the operator pressing the spring-arm 2O to one side, thus releasing' pin 21 from opening 22, the frame being then free to be swung upward.

As the frame 1 will in printing from one negative be several times swung' from printing position to horizontal position.I (for removal of prints,) it is desirable, of course, in order to secure uniformity in the several prints made from it that the frame should be returned with certainty to the same angular position relatively to the light each time a printed sheet is removed and another to .be printed is inserted in the frame. Means are provided for this purpose, in thc present 'case consisting of an adjustable stop 23, sliding in a slot 24 in arm 20 and provided with a thumb-nut 24, by which it is locked in its adjusted position on the arm. In printing from a negative the proper angular position of the frame will be first ascertained and the stop 23 adjusted and locked to arm 20, so as to engage the front face of the frame in that position, as shown in Figs. 1 and 2. Thereafter each time a fresh sheet is inserted in the frame when the frame is swung from horizontal position by the operator it will be arrested by the stop 23 in the proper angular position for printing. Vhen a new negative is inserted in the frame, the stop 23 will of course be readjusted, if necessary. l

Between the frame 1 and light-supporting frame 10 is interposed a shutter or apron 25, having a panel preferably of orange paper, said shutter beingpmo'unted so as to move vertically in a guideway formed in a frame 26 and consisting of strips 27, engaging one side of the shutter, and antifriction-rollers 28, engaging the opposite side thereof, as shown in Fig. 2. The shutter 25 is moved downwardly by its own weight and is moved upwardly by means of a cord 29, having a handle 30 at its free end and passing around a pulley 31 on support 3, thence around a pulley 32, fast to shaft 32, journaled in the upper end of frame 26, thence through eyes 33 34 fast on the shutter, and around a second pulley 35 on shaft 32 and to which the opposite end of the cord is connected. A pull on cord 29 rotates shaft 328L and raises .the shutter, which remains in its raised position, Fig. 1, until the operator releases the cord, when the shutter is returned to its lowermost position, Fig. 2, by gravity, aided, if desired, by a spring. (Not shown.)

The shaft 3 is preferably provided on opposite sides with walls 36 in line with the light, which serve as light-guards protecting the paper from the action of the light, the developing-tray being located to one side of the printing apparatus in convenient position for the operator to place his prints therein as he removes them from the frame.
